Available research suggests using Blockchain in electronic medical files to aggregate and integrate information. While reviewing authoritative articles and books, we analyzed the challenges and opportunities of using Blockchain this way. By using the specialists' opinion, completing a specialist questionnaire, using the DEMETEL technique and interpretive structural modeling (ISM) technique, this research investigated and analyzed the possibilities of using Blockchain in electronic medical files. The pair comparison technique was used to study and analyze the challenges of using Blockchain this way. The results are stated in this research. Research achievements include the design of a model using Blockchain for electronic medical files, analysis of Block chain's opportunities and challenges, measurement of the components, design and presentation of the model, and prioritizing the challenges of using Blockchain. This research suggests that the use of Blockchain in electronic medical files can reduce extra costs, create a comprehensive system for medical records to avoid additional costs, facilitate access to patient information, and reduce medical errors. The results obtained reveal that the components of immutability and the impossibility of data forgery of patient records (based on data integration in Blockchain) have the most impact on the system. Examination of the challenges reveals that blockchain technology's challenges (low speed, difficulty working with Blockchain, poor integrations between the software for various electronic health records) are of the utmost importance.

The purpose of this research was to identify and rank the factors influencing the design of the native model for assessing the effectiveness of the advertisement. Firstly, according to the research literature, the criteria and sub-criteria influencing the effectiveness of advertising have been extracted, then the Delphi triple stages were used that the panel included 20 professors and marketing experts and 30 experts from the banking industry as well as clients It is used to extract the final indexes. Then, using the Fuzzy AHP method, the ranking of the criteria is considered. The extracted criteria are: demographic characteristics, individual feelings and attitudes of the audience, apparent features of the message, message content, market characteristics, cultural, economic, design and nature of the service, advertising methods. The results of the ranking of the results showed that the methods of advertisement, the design and nature of the service, the apparent features of the message, the emotions and attitudes of the audience, the demographic characteristics, the content of the message, the economic, market characteristics, cultural, respectively ranked first to ninth dedicated.
